A separate race has been recognized by American authors as inhabiting Arizona, under the name of Spizella socialis arizonee. This bird we should expect to find in the Sierras of Durango and in Western Mexico, but we fail to detect any differences between our examples from those parts and others from the Eastern States. Moreover, a specimen from Arizona seems to us to be the same in every way, having the chestnut head of the true S. socialis. Our series, however, of this western race is hardly good enough to enable us to speak very positively, but, so far as it goes, tends to show that S. sodalis arizonee will prove inseparable from S. socialis itself. The name was based upon young birds, the striated heads of which had not given place to the chestnut crown of the adult. Though apparently a common species in Mexico, next to nothing has been written of S. socialis beyond a record of the locaUties where it' has been observed, and these extend over a large portion of that country, as far south as the mountains of the isthmus of Tehuantepec, where, according to Mr. Lawrence, specimens of both the common and the Arizona race were obtained by Sumichrast in the months of Septemberand January. In Cuba it has only once been noticed. Dr. Gundlach having shot a female specimenBIOL, centr.-amer., Aves, Vol. I., June 1886. 48
